Vascular injury is a serious but rare complication of hip procedures. Most of vascular complications reported in articles occured in vessels around hip joint and femoral artery. To date, report of popliteal artery occlusion during or after total hip arthroplasty was absent. The authors have experienced one case of popliteal artery occlusion after total hip arthroplasty. It was suspected that the cause of occlusion of this particular case was a excessive maneuvering of limb during operation and then, artheromatous plaque fracture or thrombosis made occulusion in popliteal artery. Angiographic embolectomy using a catheter was performed and circulation of limb was recovered. To reduce the risk of vascular complications after total hip arthroplasty procedure, we recommend a thorough evaluation of lower extremity circulation in risky patient. And if a vascular insult is suspected either during or soon after the procedure, then a vascular consultation with arteriography including popliteal artery should be obtained urgently. Delay in treatment could result in a deleterious outcome.

Lipoma arborescens is a rare intra-articular lesion consisting of a villous lipomatous proliferation of the synovial lining. We experienced one case of lipoma arborescens of knee which was associated with avascular necrosis of femoral head. This case report draws the attention to history, physical findings, MR images, pathologic findings and arthroscopic appearance of this rare lesion. Arthro;copically, the lesion appears as a synovial lesion with numerous fatty-appearing globules and villous projections. Although the etiology is unknown, lipoma arborescens has been described in association with osteoarthritis, rheumatoid arthritis and diabetes mellitus. MR imaging is diagnostic choice to differentiate the lesion from rheumatoid arthritis, pigmented villonodular synovitis and synovial chondromatosis in those patients who present with chronic, swollen and painfui joint. Arthroscopic removal was effective in this case and we think that treatment choice of this lesion is arthroscopic removal.

PURPOSE: The aim of this study was to investigate the efficacy of low-molecular-weight heparin (LMWH) for the prevention of venous thromboembolism in Korean patients who underwent hip fracture surgery (HFS). MATERIALS AND METHODS: Prospectively, a total 181 cases were classified into the LMWH user group (116 cases) and LMWH non-user group (65 cases). Each group was sub-classified according to fracture types as follows: 81 cases of intertrochanteric fracture (group A: 49, group B: 32) and 100 cases of neck fracture (group C: 67, group D: 33). We compared the incidence of deep vein thrombosis (DVT) and pulmonary embolism (PE) according to LMWH use. RESULTS: Of the 181 cases, four DVTs were found in the LMWH user groups (1 in group A, and 3 in group C). One case of PE was found in LMWH non-user group D. The incidences of DVT and PE showed no statistically significant differences between the LMWH user and non-user groups (p=0.298 and 0.359, respectively). In subgroup analysis, no statistically significant differences were found between groups A and B and between groups C and D. CONCLUSION: The administration of LMWH was not effective in the prevention of venous thromboembolism and PE in the Korean patients who underwent HFS.

Teriparatide (TPTD) is a bone-forming agent used to treat postmenopausal osteoporosis. Since hip fractures are related to higher morbidity and mortality rates than other fractures, efficacious osteoporosis drugs for the hip are critical. We reviewed research articles reporting the efficacy of TPTD in terms of bone mineral density (BMD), fractures prevention, changes in the outer diameter, cortical thickness and porosity, post-operative periprosthetic BMD loss, and healing of typical and atypical fractures of the hip. Data meta-analyses indicated that TPTD not only increased the BMD of the proximal femur but also decreased the risk of hip fractures. Even though TPTD increases the cortical bone porosity of the proximal femur, the bone strength does not decrease as the majority of the porosity is located at the endocortex; further, it increases the outer diameter and thickens the cortical bone.TPTD stimulates bone remodeling and facilitates callus maturity and fracture healing. There have been many reports on improving the effect of TPTD on the healing of atypical fractures; therefore it is advisable to use TPTD considering the increase benefit compared to the risk.

PURPOSE: To evaluate morphologic characteristics of the microcalcifications on mammography that were confirmed pathologically. MATERIALS AND METHODS: Forty five cases of microcalcifications on mammography (fifteen cases of benign lesion, thirty cases of maiignancy) were retrospectively reviewed. RESULTS: The number of microcalcifications within 1 cm2 were more than 5 in 22 cases (73%) of 30 malignancy and less than 5 in 11 cases (73%) of 15 benignity. The heterogeneity of microcalcifications were seen in 26 cases of malignancy (87%) and the homogeneity of microcaicifications were 11 cases of benignity (73%). The morphologic characteristics of the microcalcifications were linear-V shape in 9 cases (30%), punctate shape in 8 cases (27%), fine stippled shape in 7 cases (23%), and round dot shape in 6 cases (20%) of malignancy and, round dot shape in 11 cases (73%), punctate shape in 2 cases (13%), and linear-V shape in 2 cases (13%) of benignity. CONCLUSION: Numerous irregular microcalcifications that are heterogenous in size and morphology were strong indicators of malignancy.

The Fracture of the os calcis is quite common in relation to fracture in other tarsal bone, and fractures involving the subtalar joint may cause serious and persistant disabilities. The treatment of these calcaneal fractures remains controversial So there is no universal agreement in the treatment of these fractures, especially involving the subtalar joint. Twenty displaced intraarticular fractures of calcaneus in 15 patients were treated by open reduction and internal fixation with a plate and screws and bone graft through a lateral approach to elevate the depressed lateral portion of the posterior facet at the Inchon Chritian Hospital from Jan., 1990 to Dec, 1991. Twenty feet in 15 patients of calcaneal fractures involving the subtalal joint were treated and were clinically analysed and following result were obtained. 1. The 20 cases were classified according to the Sanders classification, 9 in type II, 9 in type III and 2 in type IV. 2. The 20 cases were treated by open reduction andinteranl fixation with plate and screws and iliac bone graft through an Sanders lateral approach. The bone graft is packed under the elevated posterior to prevent late collapse of the central fragment and to supply structral stability. 3. The preoperative average Böhler's angle was 0.4°. The post operative average Böhler's angle was 23.4° which was increased significantly. 4. Based on assessment of result of Salama, excellenwas 6, good was 7, fair was 4 and poor was 3. 5. The most common complication after treatment was persistant pain, especially beneath the lateral malleolus.
